SunShell C18
Prominent features of SunShell C18
- Unique trifunctional bonding of the C18 groups to the Silica.
- Ensures good coverage of the Bonded Silanol groups on the Silica Surface.
- Ensures symmetrical Peak shapes with minimal tailing.
- Extended surface coverage offering performance at Extreme pH ensuring high column
life.
- Higher sample loadability allowing the higher sample size.
- UHPLC performance on any HPLC using the Sunshell Core shell technology.

Comparision of Pyridine
|
Residual silanol groups make pyridine be tailing under methanol/water mobile phase
condition. Only SunShell C18 shows a sharp peak for pyridine.
It is considered that surface roughness affects column performance. Surface asperity
of ChromaNik Technologies column with 2.1 mm i.d. and 3.0 mm i.d. is 1/30 to 1/20
to compare with that of GL Sciences, YMC, Shimadzu and Waters columns. ChromaNIk
Technologies provides a column with very smooth surface which is the most suitable
for 2.6 mm core shell particle packing.

- Sunshell C18 has kept 90% retention for 100 hours under such a severe condition.
SunShell C18 is 5 to 10 times more stable than the other core shell C18.
- SunShell C18 is enough stable even if it is used under pH 10 condition. Regarding
stability under basic pH condition, there is little C18 column like SunShell C18
except for hybrid type C18. It is considered that our end capping technique leads
high stability.
- SunShell C18 can be used at the pH range from 1.5 to 10.
